25/26 Unit 2 - Dynamic Earth Test ⭐

The outer core

• A solid layer in the center of the earth
• the liquid layer the the Earth's core that is below the mantle and surrounds the inner core
• the plastic layer where convection happens
• Layer containing silicon and oxygen

Divergent zone is

• one plate goes move under another plate
• two tectonic plates that are sliding away from each other
• where hot spots like the Hawaiian Islands are formed
• two tectonic plates that are pulling away from each other, like in Iceland

Two continental plates moving toward each other

• convergent zone
• transform zone
• divergent zone
• rift zone

A deep valley in the ocean floor that forms along a subduction zone

• hot spot
• outer core
• ocean trench
• Mountain chain

Subduction zone is

• both plates move away from each other
• when two continental plates collide
• an ocean plate moves under a continental plate
• both plates are dense

When ocean crust collides with continental crust, the ocean crust _________ because if is _______

• forms a mountain
• rise, less dense
• sinks, more dense
• cause earthquakes when sliding past each other

The dense sphere of solid iron and nickel at the center of the Earth

• outer core
• inner core
• mantle
• crust

Magma that reaches the Earth's surface is called

• mantle
• magma
• lava
• ash

Two tectonic plates that are moving away from each other

• convergent zone
• divergent zone
• subduction zone
• hot spot

A plate boundary where two plates move past each other in opposite directions causing earthquakes

• transform boundary
• divergent zone
• convergent zone
• inner core
